when you use two nouns and compare or contrast them to one another

- Metaphor.

Explanation:

'Metaphor' is depicted as the term that involves 'two nouns to compare and contrast them to one another.' It is the figure of speech that primarily functions to directly establish an implicit comparison between two distinct objects or ideas in order to equate their characteristics. This assists the author to create the rhetorical effect and clarify the ideas more effectively while aids the readers to understand it comprehensively. For instance, in Shakespeare's famous quote 'All the world's a stage', he compares the world to a stage which is literally inapplicable but implies the similarity between the logistics of world and human behavior.
